IMPROV`EMENT IN LAMPS.

Specification forming part of Letters Patent No. 146,34! dated January13, `1874; application filed May 23, 1873.

of Ohio, have invented certain new and useful Improvements in Lamps, ofWhich the following is a specification:

.The invention consists of a lamp having a.

hollow handle with perforations in it for the entrance of air to theiluid, said handle being provided with a valve, so that, should the lampbe upset, `the discharge of the fluid through said handle is prevented,as will be fully hereinafter described, the object of my invention being.to improve the light and increase the safety and convenience of thedamp, allA ot' which will be understood by reference to the drawings andthe bllowing description, in Which Figure 2 is a vertical section,showing clearly the hollow handle A, which is perforated at a., wherethe air enters, and passes in the direction of the arrows tothefluid-bowl B. Heated gases generated in B pass out through the sameconduit-hamlle. al is another hole in the handle for the escape of anyHuid which may gather in the handle. The handle, being made detachable,as shown, may be` made very cheaply and rapidly. To prevent the escapeof fluid when the lamp is upset, all the joints are made tight by theuse of soft Washers, so that there can-4 not be any escape, exceptthrough the wicktube or the handle, and, to prevent the latter,

`I provide a valve, a2, in the joint Where the handle is connectedftothe reservoir, as shown in Fig. 2. rEhe seat for the valve, when thelamp is upright, is grooved, so that the air or gases will pass freelyeither Way, but the` seat in the end of the handle is conical, and, assoon as the valve rests in it from` any cause, the passage becomesclosed and the escape of the iiuid prevented. ,l

When it is desired to increase the number of burners, I attach branchfluid-tubes C (l, which conduct the. oil from t-he reservoir to theWick-tubes D D, and supply these with oxygen through the conduits E E,which, in turn, are fed by A.

Thismakes a very handsome lamp, the burners of which may be increased toany number.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In combination with the hollow handle A,

having perforations a for the entrance of air to the fluid-chamber, thecutoff valve a2, arranged and operating as and for the purposespecified.

In testimony whereof I have hereunto set my hand this 14th day of May,1873.
